The base 2, the positioning seat 3, the plug-in seat 4 and the locking assembly 6 can replace the traditional method of disassembling and assembling the sensor by rotating the bolts, which not only makes it convenient for users to disassemble and assemble the sensor, but also increases the efficiency of disassembling and assembling the sensor.

[0032] The base 2 is provided with a fixing hole 7 , through which the base 2 can be fixed to a corresponding device.

[0033] The locking assembly 6 includes a locking groove 61, which is arranged on the outside of the positioning groove 5, and is slidably connected to the limiting plate 62 in the locking groove 61; an insert rod 63, which is fixedly arranged on one side of the limiting plate 62, and the other end of the insert rod 63 passes through the inside of the positioning groove 5 and is slidably connected to the positioning seat 3; a return spring 64, which is sleeved on the insert rod 63, and the two ends of the return spring 64 are respectively fixedly connected to the locking groove 61 and the limiting plate 62; a pull rod 65, which is fixedly arranged on the other side of the limiting plate 62, and the pull rod 65 passes through the outside of the locking groove 61 and is fixedly connected It is connected to a handle 67; a slot 66, which is arranged on the side wall of the socket 4. The slot 66 is adapted to the insertion rod 63, and through the return spring 64, the socket 4 can be inserted into the positioning groove 5, so that the socket 4 squeezes the insertion rod 63, so that the insertion rod 63 and the limit plate 62 move away from the socket 4 at the same time, forming a pulling force on the return spring 64 until the slot 66 is opposite to the insertion rod 63. Under the reset action of the return spring 64, the insertion rod 63 is inserted into the inside of the slot 66, so that the socket 4 can be fixed on the positioning seat 3, thereby completing the fixation of the shell 1.

[0034] Mutually compatible chamfers are provided on the side wall of the lower end of the socket 4 and on the side wall of the plug rod 63 opposite to the socket 4. The chamfers facilitate squeezing the plug rod 63 when the plug is pressed down.

[0035] One end of the locking groove 61 is movably connected to a sealing cover, which is fixedly connected to the positioning seat 3 by a first bolt. The sealing cover is provided with a hole groove for the pull rod 65 to pass through. The insertion rod 63, the return spring 64, the limit plate 62 and the pull rod 65 can be disassembled, assembled and replaced through the sealing cover.

[0036] The socket 4 includes a positioning plate 41 and a positioning column 42. The positioning plate 41 is fixedly connected to the shell 1 by a second bolt.

A positioning pin 53 adapted to the pin slot 43 is provided on the bottom wall of the first card slot 51. The second card slot 52 is arranged below the first card slot 51 and is adapted to be arranged with the positioning column 42. Through the positioning pin 53, after the positioning plate 41 enters the first card slot 51, the positioning plate 41 can be limited, so that the slot 66 can be better arranged to correspond to the insertion rod 63, which facilitates the insertion of the insertion rod 63 into the slot 66.

[0040] The working principle of the present invention is as follows: the shell 1 is dragged so that the shell 1 drives the socket 4 to be inserted into the positioning groove 5 on the positioning seat 3, and when the socket 4 moves downward, the socket 4 squeezes the plug rod 63, so that the plug rod 63 drives the limit plate 62 to move toward the inside of the locking groove 61, and can form a pulling force on the reset spring 64 until the socket 4 is completely inserted into the positioning groove 5. When the plug rod 63 corresponds to the slot 66, the reset spring 64 resets, so that the plug rod 63 is inserted into the inside of the slot 66, completing the fixation of the socket 4, thereby completing the fixation of the shell 1.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
